A gas occupies `500 "cm"^3` at normal temperature. At what temperature will the volume of the gas be reduced by 20% of its original volume , pressure being constant ?

Explanation

To solve the problem step by step, we will use the gas law equation while keeping the pressure constant. Here’s how we can approach the solution:

### Step 1: Identify Given Values
- The initial volume of the gas, \( V_1 = 500 \, \text{cm}^3 \)
- The initial temperature, \( T_1 = 273 \, \text{K} \) (normal temperature)
- The volume is to be reduced by 20%.

### Step 2: Calculate the Reduced Volume
